The actual check is below - compilation of some snippet. > AC_TRY_COMPILE([#include <nghttp2/nghttp2ver.h>],[ If compilation and test succeed then the following assignment happens: "ac_cv_nghttp2=yes". Apparently the compilation and test failed, and the variable was not assigned. The following block > if test "x$ac_cv_nghttp2" = "xyes"; then > [ a lot of lines checking capabilities and setting some flags ] > else > AC_MSG_WARN([nghttp2 version is too old]) > fi The "if" branch was skipped and "else" branch printed the warning. I suggest you to check what is the actual value of NGHTTP2_VERSION_NUM. > checking for user-provided nghttp2 base directory...
